IPC: H01B9/02
Filed: 1966-11-16
Abstract: 1,156,829. Electric cable. KABEL-UNDMETALLWERKE GUTEHOFFNUNG - SHUTTE A.G. and F. C. EHLERS, [trading as KABELWERKE FRIEDRICH C. EHLERS]. 16 Nov., 1966 [20 Nov., 1965], No. 51360/66. Heading H1A. To reduce the quantity of wire used in a cable of the type having stranded layers of conductors these layers are laid with a reversing lay that exhibits a substantial wrapping angle only at intervals between which the conductors run parallel to, or at a very slight angle to, the longitudinal axis of the cable. At the reversal points, which may be marked on the outside of the cable, the curve of the conductors should be as sharp as possible to enable the maximum length of wire to be lifted out of position when working on the cable. The particular shape of the reversal curve can vary as required. In the apparatus for manufacturing such a cable, Fig. 6, the perforated disc 9 which rotates about cable 10 to lay the wires 11 is coupled to the driving motor 15 by a reversing gear 13 working under the control of a pulse transmitter 16. The gears are designed to operate periodically and change abruptly at a signal from the transmitter to give the required sharp reversal point.

Filed: 1968-11-01
Abstract: 1,222,230. Discus wing aircraft. D. A. PHILLIPS. 1 Nov., 1968, No. 51842/68. Heading B7W. [Also in Division F2] An aircraft has a rotatable disc 10, means to rotate the disc about its polar axis 17 and means to produce a flow of fluid in a radial direction over the surface of the disc thereby producing a lifting force on the disc in the direction of the said polar axis. The disc 10 has a convex upper surface and a central well 11 by means of which the disc is rotatably supported on an undercarriage 13 through bearings 12. A power plant 14 drives an axial compressor 16 which supplies air along the path shown by the arrows and discharges it radially over the upper surface of the disc which is rotated, also by the power plant, so that the radial flow of air over it gives rise to lift. An annular cabin pod 23 is supported above a compartment 15 containing the engine. To produce lateral movement a jet nozzle 26 is provided to which a portion of the air flows through the port 27 and which is controlled by a butterfly valve 28.

Title: Improvements in or relating to a timepiece
IPC: G04C3/00
Filed: 1967-11-16
Abstract: 1,135,009. Electric timepieces. BENRUS WATCH CO. Inc. Nov.16, 1967 [July 12, 1967], No.52279/67. Addition to 1, 101, 269. Heading G3T. The timepiece described in the parent Specification is modified to use a radio-active source emitting radiation at a constant energy level. Fluctuations in the timepiece supply voltage cause changes in the energy level at which the discriminator operates to reject pulses of a lower energy and to pass pulses of a higher energy, thus changing the number of pulses counted per second which in turn affects the accuracy of the timepiece. The present invention overcomes this difficulty by using a source emitting alpha or gamma rays having discrete energy levels so that the discriminator may be dispensed with or alternatively it may be used merely to ensure that rays at lower and higher discrete energy levels than the level of the counted rays are not counted, their energy levels being sufficiently separated so that variations in the cut-off level of the discriminator do not affect the number of rays counted. A gamma ray emitting source such as iodine 129 or uranium 233 is preferably used and is applied to the top of a metal case within which the counter is located, the case permitting penetration by the gamma rays.

Title: Improved rolling or calendering roll
IPC: F16C13/00
Filed: 1967-11-22
Abstract: 1,203,629. Rollers; clutches. PAPETERIE DE STENAY. 22 Nov., 1967 [30 Nov., 1966: 3 May, 1967], No. 53163/67. Headings F2C and F2U. A hollow roll, e.g. for rolling, calendering, embossing, glazing, coating, printing, drying, or grinding, comprises a rotatable cylindrical shell 1, a fixed or rotatable shaft 2 substantially on the axis of rotation of the shell, and, between the shaft and the shell, inflatable annular chambers 6a-6n or other resilient means capable of exerting a uniform radial pressure on the shell at any given radial plane connected to external pressure control means (not shown). The chamber pressures are controlled to maintain a predetermined axial pressure distribution along the nip between the hollow roll and a second roll 3. In Fig. 4, each annular chamber consists of a pneumatic tyre on a wheel 5a-5n the hub 12a-12n of which is secured to the shaft 2. Separate lines 9a-9n connect the tyres to the pressure control means. Shaft 2 is driven via a coupling 8, and may be bent longitudinally by forces f1, f2 to assist in obtaining the required axial pressure distribution at the nip. The tyres may be inflated and deflated to engage and disengage the drive to the shell 1. In Fig. 6 (not shown), the shaft (2) is not rotatable and the wheels are supported thereon by bearings (14a-14n). In Fig. 7 (not shown), a curved shaft (2) carrying bearings (14a-14n) for the wheels is rotatably adjustable to adjust the axial pressure distribution at the nip. In Fig. 8 (not shown), the wheels are omitted, the tyres (6a-6n) being supported directly on a large diameter rotatable shaft (2). The shell 1 may be a plain tube of steel, bronze, aluminium alloy, or plastics, and may have a resilient rubber or plastics lining. Alternatively, Fig. 9, for greater resilience, the shell may be a longitudinally slotted tube covered with a flexible sleeve (17), (Fig. 10, not shown) of rubber, plastics, or thin steel or other metal. In Figs. 11-14 (not shown), the roll is mounted inside a hollow cylindrical roll to apply the latter against a counter roll. In Fig. 11 the roll (102) has a diameter almost equal to the internal diameter of the hollow roll (100) and is rotatable. In Fig. 12 a stationary roll (112) acts via a needle bearing (117) against the internal surface of a hollow roll (111). In Fig. 13 a small rotatable roll (122) acts on the internal wall of a hollow roll (121), and in Fig. 14 a similar small roll (132) is carried at one vertex of a triangular frame (135), loose rollers (136) at the other two vertices also engaging the internal surface of a hollow roll (131).
Patent GB-532387-A (GB)
Abstract: 532,387. Ticket-issuing machines. SETRIGHT, H. R., and SETRIGHT REGISTERS, Ltd. July 17,1939, No. 20771. [Class 106 (iii)] Comprises a particular construction of ticket printing and issuing machine. The ticket strip enters the machine along a guide 18 and leaves by an aperture in the top plate 10. Knobs 41, 42, 43 are provided which set the printing wheels 24, 25 and 26 which print the time, day, and month indications, and a lever 47 sets the wheel 22 which prints the price of the ticket. To issue a ticket knob 112 is depressed which, through spindle 48, operates lever 127 which is connected to a lever 130 raising slide 134. A hooked lever 138 can then engage behind a projection 137 on the slide and latch it. Spindle 48 also operates a switch 118 which starts the driving motor of the machine which rotates member 71. The movement of the lever 138 allows a dog member 87 (Fig. 6) to be rocked to engage teeth 84 and lock member 71 on shaft 69. The latter operates the printing platen 21 by means of a cam 93. It also subsequently operates the strip feed roller 19 by gearing actuated by a mutilated gear 92. A shaft 148 is also operated through bevel gears 146 and 147. This shaft through a skew gear 149 drives ink ribbon mechanism and through bevel gears 151 and 152 drives counting mechanism. The movement of the arm 47 to select the value of the ticket will operate a slider 168 through gears 49, 177, 172, and screw 170. The slider moves a gear on the shaft driven by bevel 152 and couples it with the counter for the particular ticket value. When the operating shaft 69 of the machine makes a complete revolution a cam thereon rocks an arm 143 and unhooks a lever 138 and allows spring 136 to lower slide 134. The movement of lever 138 displaces the tail 89 of the dog member 87 and uncouples shaft 69 from member 71. When the slide 134 is released spindle 48 rises and cuts off the driving motor. In a modification the member 71 may be operated by a manual member instead of a motor.
